Radio 4 BBC World Service News Hour veteran Robin Lustig is to leave radio after 23 years.

Lustig, 64, has expressed interest in "returning to the field" of reporting.

Having interviewed Tony Blair, Nelson Mandela and Kofi Annan, the presenter can boast an extensive and impressive broadcasting career.

Speaking about his resignation, Robin said: "This has been an immensely difficult decision, but I think now is a good time for me to bow out and see if I'm still capable of doing anything else."

"It's been a huge privilege to be part of the Radio 4 and World Service families for more than two decades, but I hope now to have an opportunity to return to my first love: reporting from the field and getting mud on my boots."

Radio 4 presenters Charlotte Green and Harriet Cass have also taken voluntary resignation this year, accruing 74 years of experience in total.
